The Pico PQ071 Sight block kit contains the sight block (an updated version of the one used in our Volkswagen caddy case study), a stop valve for testing a negative pressure fuel pump under load, and 3 sets of hose barbs for connecting to different size fuel hoses.

The kit is intended for diagnosing problems with low-pressure fuel systems up to the inlet of any high-pressure pump. The maximum safe working pressure for the sight block is 7 bar (gauge pressure).
